Digital signal implementation of the discrete Wigner distribution function
Raouf N.G. Naguib, Alan Kwabwe, Robert A. King · Canadian Electrical Engineering Journal · 1985
A computationally efficient representation of the discrete Wigner distribution function is suggested. It allows the investigation of the spectral properties of a real analytic signal to be performed and the possibility of its recovery from the distribution. A 2-D discrete representation is also introduced with special applications to image processing.
